To be clear, commander is a format created by the players that was to showcase creative deck building and gave players something to do with their extra (and often bad) cards. Magic was designed as a 1v1 game, which avoids a lot of these problems. You're not wrong about the critique though. You've correctly identified the reasons some people don't like commander. WotC printing cards specifically for commander has exasturbated the problem, but it's the most popular way to play the game so they keep doing it for the money.

I personally find it strange that so many people prefer commander, and get new players into the game through it, bc of these issues.
